Laurent, My Pentair Intelli-Flo is one of the quietest pumps in the market, but not enough to my satisfaction. So I have searched the internet for months to find a product that would reduce the noise. I have to say, your product is the only one in the market that has successfully reduced the noise level by 80% and I thank you for it. Now I can enjoy the serenity of my backyard. Your service and dedication to resolve my noise issue was excellent considering that my installation needed to be customized. Best regards
Herb (California)
